The focus of mathematics is the continued explicit emphasis on teaching the content and proficiencies of the Western Australian Curriculum through structured numeracy blocks and evidence based pedagogy. Students will continue to learn ways in which to sue their ideas about number and algebra, measurement and geometry and statistics and probability to understand, problem solve, reason and develop fluency of mathematical content and assist their learning across the curriculum. Teachers utilise the Origo- Stepping Stones mathematics resource. Leinster Community School also uses Mathletics which is an online student resource aimed at improving mathematical skills and automaticity.
